The Science and Uses of Distilled Water

Distilled water is created by heating water to its boiling point, allowing the steam to rise, and then cooling it down to convert it into liquid. This method is one of the most efficient ways to purify water, which makes it suitable for various industrial, medical, and other applications that require ultra-clean, non-mineralized water.

Historical Context of Water Distillation

Water distillation isn’t a new concept. Its roots trace back to the third century AD when Alexander of Aphrodisias used it to desalinate seawater. This age-old technique has evolved over centuries, enhancing its efficiency and effectiveness with modern technology.

The Process of Making Distilled Water

Three main methods can be used to distill water: simple, multi-stage flash, and fractional distillation. Simple distillation involves boiling the water and collecting the condensing steam.

Multi-stage flash distillation uses high pressure to lower the boiling point, turning the liquid into steam without heating. Fractional distillation repeats the heating and condensation steps at different temperatures, although this method is rarely used for water.

Applications of Distilled Water

Distilled water’s purity makes it highly versatile. It sterilizes medical equipment, powers lead-acid batteries, and maintains automotive cooling systems. Its lack of minerals and contaminants makes it ideal for skincare products, preserving canned goods, and cleaning laboratory equipment.

Distilled Water in the Cosmetic Industry

Most cosmetic products require water free from microbes, toxins, and pollutants. Distilled water meets these requirements, making it the best choice for this industry.

Role in Automotive and Industrial Equipment

Distilled water helps prevent corrosion and build-up in devices like lead-acid batteries and automotive cooling systems. Its lack of mineral deposits makes it an excellent choice for these applications.

Distilled Water in Medical Practices

It is perfect for sterilizing medical instruments due to its high purity level. Surgeons use it to prevent infections and cross-contamination. Dentists use it to rinse mouths and wash away bacteria. It’s also preferred in Continuous Positive Airway Pressure (CPAP) machines, as it prevents bacterial growth.

Distilled Water in the Food Industry

Distilled water is used in the canning process to maintain flavor. Salts and minerals in non-distilled water could alter flavors, hence distilled water’s preference.

Distilled Water in Aquatics

Tap water contains minerals and chemicals potentially harmful to fish in aquariums. On the other hand, distilled water has adjustable qualities such as pH or salinity, making it suitable for aquatic life.

Exploring the Advantages of Distilled Water

Distilled water offers several health benefits, particularly those with compromised immune systems. It can also play a vital role in successful cancer surgeries.

Individuals with compromised immunity are more vulnerable to health issues arising from chemical pollutants such as

  • Cancer patients undergoing chemotherapy.
  • Organ transplant recipients
  • People living with HIV/aids or other immune disorders.
  • Certain groups of elderly and infants

Distilled water is less likely to carry contaminants that could pose risks to these individuals as compared to standard municipal water sources.

Moreover, it is free from biological contaminants like the cryptosporidium parasite, which can be especially harmful to immunocompromised individuals.

A 2013 report by Kerri A. Thom from the University of Maryland’s suggests drinking distilled water, can help shield high-risk patients from waterborne infections.

There’s also evidence to suggest that drinking distilled water can aid in certain cancer surgeries. A study conducted in 2004 by the Department of Colorectal Surgery at West Suffolk Hospital in the UK investigated the potential benefits of using distilled water instead of sanitizers during colorectal cancer surgery.

The study found that distilled water demonstrated effective tumoricidal properties in laboratory cultures. However, current surgical procedures would need modifications to allow for longer exposure of cells to distilled water.
